My father said it has been around his whole life so it is at least 75=80 yrs old.
It is marked 0.5l on rim and on bottom is GERMANY 1247 inprinted in the mold
The toad is so life like!
This is actually a picture I found on the internet but it is the same mug acording to my father.
Thank you for any info...we have always wondered about it.
